MACHINE FOR CLEANING, SEPARATING, AND GRADING GRAIN.

SPECIFICATION forming part of Letters Patent No. 253,380, dated February7, 1882.

Application filed October 3,1881. (No model.)

To all whom it may concern:

Be it known that I, JAMES M. HAWIIEY, of Odin, iirthe county of Marionand State of Illinois, have invented certain new and useful Improvementsin Machines for Oleanin g, Separat ing, and Grading Grain and Seeds, ofwhich the following is a specification.

Reference is to be had to the accompanying drawings, forming part. ofthis specification, in whichsimilar letters of reference indicatecorresponding parts in all the figures. Figure 1 is a sectional sideelevation of my improvement. Fig. 2 is a plan view of the same, thecover and reel being removed and parts being broken away. Fig. 3 is arear end elevation of the same. Fig. 4 is a front end elevation of thesame. Fig. 5 is a sectional end elevation of the same.

The especial object of this invention is to separate wheat from othergrains andseeds and grade the wheat according to the size of itskernels, and also to separate timothy and red-top seeds.

Theinvention consists in a novel construction and arrangement of parts,as hereinafter fully described, and pointed out in the claims.

A represents the legs of the machine, which are arranged in pairs, thelegs of each pair' crossing each other a little above their'centers.

Tothe inner sides of the upper parts of the, legs-A, a little above thepoints of intersection, are attached two boards, B, the lower edges ofwhich are at a little distance from each other, and which, in connectionwith the legs A, form the frame of the machine. The space between theboards B is divided into a series of hoppershaped discharge-spouts, O,by a number of V-shaped plates, D, attached to the said boards. The endsof the boards B are connected by plates E, attached to them.

The case of the machine is made in hexagonal form, as shown in Figs. 3,4, and 5, and has'an opening or slot along one angle, which angle fitsinto the space between the upper edges of the two boards B, as shown inFigs. 3 and 5. The case is made in two equals parts, F G,'the plane ofdivision extending along the central lines of the vertical sides of thesaidcase."

In the centers of the adjacent edges of the ends of the parts F G of thecase are-formed notches to serve as bearings for the journals of thereelshat't H. The notch in the tail end of the upper part, G, of thecase is elongated, as shown in Fig. 3, so that the tail end of the reelcan be raised and lowered to adjust the inclination of the said reel asthe work to be done may require.

To the shaft H are attached pairs of radial arms I, and to the outerends of each pair is attached a rib, J. The ribs J are made thin upontheir inner sides, to which sides the reel Wire-cloth is attached, sothat the said ribs may occupy as little as possible of the said cloth.Five, more orless, different numbers or grades, K K K K K of wire-clothare used, the finest cloth being used at the head of the reel, and thesaid cloth gradually increases in coarseness toward the tail of the saidreel. The cloth K is made of such fineness of mesh that only seeds andsubstances smaller than cookie-seed and the smallest kernels of graincan pass through. The cloth K allows cockle-seed,the smaller grains, andimperfect and shriveled kernels of wheat to pass through. The cloth Kallows large cookie-seed, larger kernels of rye, and the smallestkernels of wheat to pass through. The cloth K allows the mediumsizedkernels of wheat and any large kernels ofother grain that may be withthe wheat to pass through, so that only the largest kernels of wheatwill pass to and through the cloth K If desired, the grain that passedthrough cloth K can be again run through i the machine, with the reeladjusted at a less inclination and revolved at a less speed, to furtherseparate and grade the grain by taking out the largest kernels.

The inclination of the reelH l J is regulated by means of the lever 9and the lever-cam 10. The lever 9 is pivoted at one end to the uppercorner of the tail end of the lower part, F, of

the case, and rests at or near its middle part upon the face of the cam10, which is pivoted to the tail end of the said lower part, F,ot' thecase.

In the middle part of the upper edge of the lever 9 is formed a notch orhalf-bearing to receive the journal of the reel-shaft H. The cam 10isprovided with a handle or lever'for convenience in turning it to raiseand lower the lever 9, and thus vary the inclination of the reel as thework to be done may require.

To the inner surface of the lower part, F, of the case are attachedflanges L, to prevent the grain from the different cloths from mixin andto guide each grade of grain to its own discharge-spout (J, where it isreceived in bags suspended beneath the spouts O by hooks M, attached tothe boards B or in other suitable receivers.

The joints between the different numbers of cloth are covered,strengthened, and protected by bands N, attached to the inside of thereelribs J. The tail end of the reel is strengthened and the outer edgeof the cloth K is supported by a band, 0, attached to the outer sides ofthe ends of the ribs J,and to the edge of the cloth K", midway betweenthe ribs J, as shown in Fig. 5.

To the inner side of the ends of the ribs J, at the head of the reel, isattached the outer edge of a ring-plate, P, which strengthens the reeland prevents any grain from escaping at the head of the said reel.

To the inner sides of the parts of the reelribs J, that carry thecoarsest cloth, K are attached pins or teeth Q, as shown in Fig. 1,which teeth stir up the grain as it passes upon and across the cloth Kso that the kernels of wheat will readily pass through the meshes of thesaid cloth. Straw and other coarse refuse that may enter the reel withthe grain are raised by the teeth Q to a suflicient height to allow themto fall upon the inclined spout It, suspended from the reel-shaft H bythe bars or straps S and collars T, as shown in Figs. 1 and 5. The spout1t conducts the coarse refuse dropped into it to the tail end of thereel and discharges it through the opening U, between the tail ends ofthe boards B upon the plateV, attached to the upper end of the screen W,down which it slides to the floor or into a receiver placed at the lowerend of the said screen.

To the end of the board B, next the discharge end of the screen V, isattached a plate, X, which projects partly across the opening U, so asto turn the coarse refuse passing through the said opening and cause itto fall upon the upper part of the plate V. The screen W is slightlycurved downward, as shown in Fig.3, to prevent straws or other longsubstances that may be passing lengthwise down the said screen W fromcatching in the meshes of the said screen. Anykernels of wheat that maypass out to the screen W with the coarse refuse drop through the meshesof the said screen into a receiver placed beneath it, so that all thewheat will be saved. The screen Wis suspended by thebailsuo. The ends ofthe bailuareattached to the upper ends of the side bars of the saidscreen W, and its center is hooked upon a hook or other support, w,attached to one of the boards B. The ends of the bail a are attached tothe middle parts of the side bars of the screen XV, and its center ishooked upon a hook or other support, 00, attached to the side of thelower part, F, of the case. Several hooks w are attached at ditferentheights to the side of the part, F, of the case, so that the inclinationof the screen W can be adjusted by changing the bail o from one toanother of the hooks w. The screen V is agitated by a lever, Y, thelower end of which is passed through the mesh at the upper outer cornerot'the wire-cloth of the screen W, or through a keeper attached to thesaid screen, or is connected with the said screen by a pivoted rod. Thelever Y is made with an offset in its middle part, and at the saidoffset passes through and is pivoted to the end of the lower part, F, ofthe case. The upper end of the leverY projects across the reel-shaft Hat its tail end, so as to be struck and vibrated by staples Z or otherprojections or cams attached to the said shaft H. Upon the journal ofthe reel-shaft H is formed the crank a, by means of which the reel isrevolved. The grain is fed into the reel H I J from the hopper b, theinner side of which is vertical, and has its side edges protected andbeveled to fit against the beveled edges of the vertical cleats 0,attached to the end of the lower part, F, of the case, so that the saidhopper can be readily removed. The outer part of the hopper 1) issupported by the brace (l, the upper end of which is attached to theinclined outer side of the said hopper b, and its lower end rests upon ahorizontal cleat, 6, attached to the end of the lower part, F, of thecase, as shown in Figs. 1 and 4.

The hopper b is provided with a falsebottom,f, to serve as a spout toguide the grain to the discharge'opening of the .said hopper, and alsoto relieve the shoe 7 from having to support the weight of the saidgrain. The shoe 9 is pivoted by pivots g at its upper end to the outerside of the hopper b, as shown in Fig. 4, and its lower end passesthrough an aperture in the end of the part F of the case, and projectsinto the head of the reel H I J, so as to deliver the grain within thesaid reel, and so as to be struck and agitated by a projection or cam,h, formed upon or attached to the inner edge of the ring flange or plateP, attached to the head ends of the reel-ribs J, as clearly shown inFig. 4.

The escape of the grain from the hopper b is regulated by a gate, 1,which slides in a groove formed in, or in a keeper, 2, attached to theinner surface of the vertical inner side of the said hopper b.

To the upper part of the outer side of the gate 1 is attached a block,3, which is inclined upon its lower edge to rest upon the inclined upperedge of a sliding bar, 4. The lower edge of the bar 4 is straight andrests upon the upper edge of the vertical inner side of the hopper 1),so thatithe gate 1 Will be raised and lowered by the longitudinalmovement of theslid= ing bar 4. The sliding bar 4 is kept in place byalong keeper, 5, attached to it, and through which the gate 1 passes.

When the machine is to be used for separating timothy-seed and red-topseed the reel H I J is replaced by a reel of about half the length ofthe reel HI J, and which is provided with a. wire-cloth of such finenessof mesh that nothing larger than timothy and red-top seeds can passthrough it; or the reelH I J for about half its length is covered withthe said wirecloth, and a short screen, i, of a little greater diameterthan the reel H I J, is placed upon the head end of the said reel H I J,and is secured in place by screws or bolts j, passing through theprojecting ends of its ribs andinto or through the ribs J of the saidreel. WVith this construction, when the grass-seed is fed into the reelH -I J the timothy and red-top seeds and everything smaller than thesaid seeds will pass through the reel H I J and everything smaller thanthe said seeds will pass through the meshes of the screen or outer reel,i, and escape; but the timothy and redtop seeds will drop from the inneredge of the screen 1' through the hoppers G, and will be received uponthe upper part of the screen k, placed beneath the said hoppers O.

The screen It is suspended from the machine by the bails l m. y The endsof the baill are attached to the upper ends of the side bars of thescreen It, and its center is hooked upon a hook, it, or other supportattached to one of the boards B. The ends of the bail m are attached tothe middle parts of the side bars of the screen k, and its center ishooked upon a hook, 0, or other support attached to the side of thelower part, F, of the case. Several books, 0, are attached to the sideof the case at different heights to receive the bail m, so that theinclination of the said screen 7c can be regulated by hooking the bailon upon a higher or a lower hook, o. The screen kis made of suchfineness of mesh that the red-top seed can pass through it, but not thetimothy-seed.

To the lower edges of the side bars of the screen is attached a plate orcover, 10, extending from the upper end of the said screen nearly to itslower end, and which is designed to receive the red-top seed and conductit into a box or other receiver placed beneath the lower edge of thesaid cover 1).

To the upper edges of the side bars of the Screen is is attached a plateor cover, q, extending from the lower end of the said screen is nearlyto its upper end, space being left between its upper edge and the upperend of the screen 70 to receive the seeds. The cover (1 is designed toprevent timothy-seeds from bounding'or jumping out of the screen and tokeep the seeds close to the wire-cloth of the said screen.

r is the casing, s is the fan-shaft, and t are the fans, of afan-blower. The casing r and the bearings for the journals of thefan-shaft s are attached to supports secured to the frame A B of themachine in such positions that the air-blast will strike the seeds asthey fall from the hoppers O and blow 0E any light impurities that maypass out of the machine with the said seeds. To the end of the fan-shatt sis attached a cone-pulley, 6, around which passes a band, 7. The band7 also passes around a cone-pulley, 8, attached to the reel H I J, sothat the fan-blower will be operated from the said reel.

The fan-blower r s t will not be neessary when the machine is used forgrading grain.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patent 1. In amachine for cleaning, separating, andgrading grain and seeds, the combination, with the boards B, providedwith the openings U and the plate X, the case F, spout R, and the reel,of the screen W, having plate V, the bails m), and its operatingmechanism, substantially as and for the purpose set forth.
